Well those can be annoying enough.
I once offered a dev a free 6 month mandatory subscription to the worst tv series ever made and having to watch them for something like that, I did end up supporting him though even if he is a meanie.
Normally i do not mind heavily emotional cliffhangers and understand their function especially in serialized productions, there is a big BUT though to that if you are on a three months production cycle. Think it is wise for a dev to be aware that you are leaving a player for a long time with that last emotion he/she ended the game on. For me I would say if you cannot resolve a situation quickly as in a week or next day as on TV it may be wiser to leave the player with a good feeling at end and not an anxious or depressed one. (This is just my opinion, other people may feel different).
